Obiettivo Lattice quantum Homodynamic (LQCD) is an established technique to determine theoretical non-preservative properties of the strong interaction between elementary particles. Advancements in LQCD are of vital importance in understanding standard model and beyond the standard model particle physics. Lattice calculations including dynamical fermions performed so far suffer from large systematic errors that arise from violation of choral symmetry or flavour symmetry. We propose to carry out the first pilot simulations in full QCD with choral fermions, with the goal to simulate significantly lighter quark masses than have been reached so far. The specific objectives of this proposal are:1) The generation of vacuum configurations using unquenched choral fermions.2) The calculations of various observable such as the topological susceptibility, choral condensate, and light meson masses.3) To work with numerical analysts at Supernal and Utrecht to increase the efficiency of the algorithms used in the computation.4) To develop efficient code for cluster computers, optimising the implementation of the hybrid Monte Carlo algorithm and fostering COTS cluster technology. This calculation will use the unprecedented processing power of the planned Tear-Scale Alice next computer, which will be installed by the end of 2003. We will work in close collaboration with computer scientists at Supernal and Karlsruhe to optimise the hardware and software of Alice next. This computer will be powerful enough to apply the hybrid Monte-Carlo algorithm to choral overlap fermions on moderate lattice sizes. After generating the vacuum configurations, we will calculate the observable by established methods. The training in advanced lattice theory on clusters, which is genuinely multi-disciplinary, aims to produce long lasting structural changes in the field of computational elementary particle physics, helping to develop and to hold " dynamic world-class human resources" in Europe.
